Buy a grain mill when you want control over your crush or regularly use unmilled malt. If you brew occasionally and your supplier mills grain to suit your system, owning a mill may add storage and cleaning work without solving an immediate problem.
For an all-grain brewer, the goal is a suitable crush rather than simply the finest grind possible. Your mash and filtration setup affects how finely you can mill while maintaining manageable runoff.
Two options to compare
| Option | Good fit | Tradeoff |
|---|---|---|
| MRbrew adjustable two-roller mill | A basic adjustable home setup | Verify the base and drive arrangement |
| Kegco KM11GM-3R | Larger hopper and a three-roller design | More bulk; compare total setup cost |
MRbrew: adjustable two-roller option
The linked MRbrew model lists an adjustable roller gap, a 7 lb hopper and a wooden base. It can be hand-operated or used with a compatible low-speed drill according to the listing’s instructions.
Why consider it: a basic adjustable design for milling your own malt. Tradeoff: confirm that the base fits your receiving container and that the included drive hardware matches the way you plan to operate it. Do not assume every drill attachment will fit.

Kegco KM11GM-3R: three-roller option
Kegco’s KM11GM-3R has an 11 lb hopper and three rollers. The first gap starts the crush, followed by a second adjustable stage. The current Beverage Factory listing describes a metal base and hand-crank or drill operation.
Why consider it: a larger hopper reduces refilling when your grain bill exceeds a smaller mill’s capacity. Tradeoff: three rollers do not automatically improve your beer. Check the weight, space, adjustment procedure and cost against the amount you actually brew.

What to check before ordering
- Gap adjustment: look for a repeatable setting rather than guessing each batch.
- Base: confirm what is included and how the mill stays secure over a bucket.
- Drive: match the handle or drill connection to the supplied instructions.
- Hopper: compare capacity with your grain bill; a large hopper is convenience, not higher extraction by itself.
- Maintenance: check the maker’s cleaning and lubrication directions for the actual materials.
Start with a small test crush
Inspect a sample of your malt before milling the whole batch. Adjust within the manufacturer’s limits and record what works with your system. Grain should feed smoothly, and the mill must remain stable. Keep fingers, hair and loose clothing away from moving rollers.
Use the intended brewing grain; a malt mill is not automatically suitable for hard corn or oily ingredients. Keep it dry and clean it according to its instructions. Compare your measured extraction and runoff over several batches rather than judging the crush by appearance alone.
